ABSTRACT:
An apparatus for recording a digital information signal and a subcode signal in slant tracks (FIG. 1) on a record carrier (140), includes an input (111) for receiving the digital information signal and an input (123) for receiving the subcode signal. Portions of information of the subcode signal are accommodated into subcode signal blocks (FIG. 2) and portions of information of the information signal are accommodated into information signal blocks (main sync blocks, FIG. 1). The subcode signal blocks and the information signal blocks are combined into a composite signal for recording the tracks on the record carrier. Time code signals are generated and accommodated in specific subcode signal blocks in the subcode signal recording portion having sequence numbers that satisfy the following formula:
